Jujube trees are suitable for planting in spring and autumn. If there is no severe cold in winter, the average temperature in 65438+ 10 is above 8 degrees below zero, and it can be planted in autumn. In the south of China, it is warmer in winter and suitable for planting in spring.
Jujube trees have strong adaptability to the environment, like sunny environment, like dry and cold climate, are not strict with soil requirements, like fertile slightly alkaline or neutral sandy loam, and are resistant to certain drought and barren. They are generally distributed in plains, sandy land, valleys and mountains, and grow in areas below 1700 meters above sea level.
Jujube growth cycle management;
1. Temperature management: The most suitable temperature for jujube growth is about 15 degrees Celsius per year. The temperature of jujube buds should be kept between 13℃ and 15℃ when they germinate, 17℃ when they begin to grow leaves, and 22℃ to 25℃ when they bloom and bear fruit.
2. Fertilization management: sufficient nitrogen supply is needed in the germination stage, nutrient absorption increases in the flowering stage, the demand for nitrogen, phosphorus and potassium increases, the root system grows vigorously in the young fruit stage, the demand for fertilizer and water increases, and the demand for nutrients reaches the peak in the fruit expansion stage. In early spring, a small amount of urea, boric acid, potassium dihydrogen phosphate and growth regulator can be sprayed on the whole tree, which is of great significance to reduce flower drop and fruit drop, increase production and improve quality.
